Influence of the saturation state of recycled sand on mortars compressive strength

This paper investigates the water content of pre-saturated recycled concrete aggregates (RCA) that has a diameter of 1-4 mm called recycled sand (RS), in order to determine the degree of saturation of the RS. It also puts forward the effects of the saturation state of the RS on the mechanical properties. For this matter, experiments were...

Dry and hydraulic extensile fracturing of porous impermeable materials

Extensile hydraulic fracturing of mortar is investigated and compared to extensile dry fracturing of sandstone. The extensile fracture experiments have been performed in a Hookean cell in deformation control. The cell allows for axial loading and radial fluid pressure loading of cylindrical specimens. Variables in the experiments are the load...
